  • a conventional paper cassette comprises a cassette body 10 in a cabinet type, within which a plurality of papers are contained, a paper arranging guide 11 for arranging trailing edges of the papers in order while moving in a horizontal direction along the bottom of the cassette body 10 , and a guide plate 13 installed on an inner side of the cassette body 10 , wherein the leading edges of the papers come into contact with the guide plate 13 .
  • the paper pick-up unit comprises a pick-up lever 21 installed above the cassette body 10 to be pivotable within a predetermined range of angle, and a pick-up roller 23 provided at an end of the pick-up lever 21 to be rotationally driven.
  • the pick-up lever 21 is pivoted and lowered due to its weight and the weight of the pick-up roller 23 , the pick-up roller 23 contacts with the top of the papers loaded in the cassette body 10 .
  • the pick-up roller 23 is rotationally driven in this state, the uppermost paper is picked up by the pick-up roller 23 . Then, papershaving leading edges in contact with the guide plate 13 , are separately fed sheet by sheet due to frictional force produced by such a contact.
  • the operation of separating and picking up the papers depends on the angle in which the guide plate 13 contacts with the leading edges of the papers and a paper feeding force generated by the rotation of the pick-up roller 23 . Therefore, the distance A between the contact area of the pick-up roller 23 and the paper and the guide plate 13 is a very important design factor.
  • the pick-up lever 21 will be pivoted downward and the pick-up roller 23 will be displaced as indicated by phantom lines.

  • the guide surface comprises a first slope which forms a first angle with respect to the leading edges of the papers loaded in the cassette body contacts with the first slope, and a second slope interconnecting the first slope and the bottom surface of the cassette body, wherein the second slope forms a second angle with respect to the leading edges of the papers loaded in the cassette body and contacts with the second slope.
  • the first slope comprises a greater inclination than the second slope.
  • a boundary between the first slope and the second slope is positioned at a height corresponding to approximately a half of a paper loading capacity of the cassette body.
  • the paper cassette further comprises a friction pad installed on one of the first and second slopes to provide a frictional resistance when the leading edges of the papers contact with the friction pad.

  • the pick-up roller 23 is rotatably installed at an end of a pick-up lever 21 , which is installed in a printer body 30 to be pivotable within a range of angle.
  • the pick-up roller 23 is rotated by receiving power through a power transmission mechanism (not shown), and contacts with and picks up an uppermost paper among the loaded papers P.
  • the pick-up lever 21 is pivotable up and down about a pivot axle 21 a connected to the printer body 30 .
  • the pick-up lever 21 is lowered due to its weight and the weight of the pick-up roller 23 and the pick-up roller 23 contacts with the papers P.
  • the construction and operation of the pick-up lever 21 and the pick-up roller 23 are well known in the art of printing apparatus and thus detailed description thereof is omitted.
  • the cassette body 40 is removably installed in the printer body 30 .
  • the cassette body 40 is typically capable of being loaded with several hundreds of papers P.
  • a sidewall inside the cassette body 40 is formed inclined in an angle capable of supporting the guide plate 60 .
  • the paper arranging guide member 50 is installed to slidably move in a horizontal direction along the bottom of the cassette body 40 .
  • the paper arranging guide member 50 arranges trailing edges of the papers P in a predetermined form.
  • the paper arranging guide member 50 arranges the trailing edges of the papers P to correspond to the shape of the guide plate 60 . Therefore, the paper support surface 51 of the paper arranging guide member 50 comprises a shape complementary to that of the paper guide surface 61 of the guide plate 60 .
  • the paper support surface 51 comprises a curved surface with a predetermined curvature radius.
  • the lower end of the guide plate 60 is fixed to the bottom of the cassette body 40 and the upper end is fixed to the upper end of the cassette body 40 .
  • the guide surface 61 provided on the guide plate 60 maintains a constant spacing in relation to the pick-up roller 23 in the paper feeding direction, i.e., in relation to the horizontal direction of the papers as the pick-up roller is moved. Therefore, the guide surface 61 comprises a curved surface having a predetermined curvature radius.
  • a center of the predetermined curvature of the guide surface 61 corresponds to a pivot center of the pick-up lever 21 and the predetermined curvature radius of the guide surface 61 is larger than a pivot radius of the pick-up lever 21 about a pivot axle 21 a .
  • a sidewall inside of the cassette body 40 comprises a rounded engaging surface 41 capable of supporting the guide plate 60 .
  • the guide plate 60 is installed on the engaging surface 41 to be tightly contacted therewith, it is possible to prevent the guide plate 60 from being deformed by repeated compressive forces applied by the papers as being picked up. Therefore, the guide plate 60 is formed of a metallic material to minimize the wear caused friction.
  • the paper support surface 51 of the paper arranging guide member 50 comprises a curved surface having a curvature radius relative to that of the guide surface 61 . Therefore, the trailing and leading edges of the papers P loaded within the cassette body 40 are roundly arranged and supported by the paper support surface 51 and the guide surface 61 .
  • the distance between the pick-up roller 23 and the guide surface 61 may be constantly maintained even if the pick-up roller 23 is lowered due to its weight and its position is changed as the papers P are continuously picked up and fed by pick-up roller and thus the quantity of the papers P is reduced. That is, even if the position of the pick-up roller 23 is gradually changed as indicated by phantom lines in FIG. 2, the distance A (shown in FIG. 3) is constantly maintained. Accordingly, it is possible to pick up all the papers from the uppermost paper to the lowermost paper with a constant pick-up force. Further, because the frictional resistance applied to the leading edges of the papers is constantly maintained, it is possible to normally feed papers sheet by sheet. Since the distance A is constantly maintained, it is possible to prevent two or more papers from being concurrently picked up.
  • the paper cassette for a printing apparatus comprises a cassette body 140 to load papers P therein, a paper arranging guide member 150 slidably installed within the cassette body 140 , and a guide plate 160 installed on a sidewall within the cassette body 140 to face with the guide member 150 .
  • the construction of the cassette body 140 is similar to that of the cassette body 40 shown in FIG. 2.
  • the engaging surface 141 for supporting the guide plate 160 is different from the engaging surface 41 of the cassette body 40 in shape.
  • the engaging surface 141 has a shape corresponding to that of the guide plate 160 to be described later.
  • the papers loaded in the cassette body 140 are picked up by a pick-up unit including the pick-up roller 23 and the pick-up lever 21 .
